Heap leaching HL is a flexible and economic mineral processing method, commonly used to extract gold from low grade gold ores. In this process, ore is firstly crushed to fine particles. By spraying leaching solution to the large piles, the gold containing solution is leached. Then used the method of carbon adsorption, zinc powder displacement device and so on to separate gold from the liquid.
Normally, the ore is crushed and agglomerated prior to heap leaching. High grade ores and ores resistant to cyanide leaching at coarse particle sizes, require further processing in order to recover the gold values. The processing techniques can include grinding, concentration, roasting, and pressure oxidation prior to cyanidation. History. The smelting of gold began sometime around 6000 3000
